The effect of dopant concentration on structural morphology and yield of products were investigated using the dopants 1,5-Naphthalene disulfonic acid and Naphthalene sulfonic acid. A Keithley 6571B High Resistance Meter and Electrometer was used to evaluate the conductivity of different molar ratios of PPY/1,5NDSA and PPY/NSA-APS utilising a four- probe setup. The conductivity of polypyrrole films doped with different sulfonate derivatives of naphthalene decreases as the number of sulfonate groups in a doped molecule grows in the same aromatic ring (naphthalene). The polypyrrole films were characterised using Fourier transform infrared spectroscopy (FTIR), NMR spectroscopy, SEM examination, and XRD analysis.
